IMac :: Apple I5 And I7 27" IMacs Do NOT Support High Speed Ethernet?

Feb 28, 2010

I found this article below when searching on iMac i7 info.We took delivery of the brand spankin' new 27" i7 iMac last week and connected it immediately to our Final Share SAN in about 5 minutes for video editing. Quick tests showed the SAN was connected and working fine.Then today I started really editing on it and I'm dropping frames every 10 to 30 seconds. Now it appears the ethernet controller that is in the new Mac cannot support the speeds necessary to edit video via the SAN. Our 2 year old iMacs can, but the brand spanking new, most powerful iMac cannot.I'm at a loss as to how Apple can improve every aspect of this machine, including the absolutely stunning 27" LED backlit display, but then cut back on something as simple as an Ethernet Controller that should be designed to work with today's equipment running high speed internet instead of stepping backwards to the speed of older model PowerMac machines.

Hardware :: Adding A Webcam To Imac Desktop - High Speed Usb 2.0 Vs Full Speed

Dec 20, 2007

I am interested in adding a webcam to my desktop Imac (power pc)- Isight is no longer available- an option that I found is the Ecamm Image- but apparently it is USB and not firewire and it will only run with high speed usb- how do I know which type is on my computer? I checked system profiler but quite frankly wasn't sure of the designations.. does anyone have any experience with this camera, by the way? is USB 2.0 by definition "High Speed"?

OS X :: Apple Open CL As High-speed Computing Standard

Jun 17, 2008

Apple has signed on to an industry-wide alliance that will see many companies, including some of the Mac maker's processor and video card suppliers, work together to develop an open format for accelerating specialized computing.Dubbed the Compute Working Group, the organization managed by Khronos Group has been formed this week and includes Intel as well as AMD and NVIDIA, both of whom compete against each other to supply video hardware for Macs in addition to other PC makers. ARM, Motorola, and Samsung are also among the involved manufacturers.The group's focus will be to develop widespread standards for calculating "heterogeneous data" regardless of whether it's onboard a conventional central processor or on a new wave of video cards that can handle some specialized calculations in addition to their normal graphics duties. Like the OpenGL standard, any future standard would be publicly documented and royalty-free.

MacBook Pro :: Does The Apple Thunderbolt To Ethernet Dongle Support Promiscuous Mode

Jul 2, 2012

Does the apple thunderbolt to ethernet dongle support promiscuous mode ? I need to use the new Retina MBP as a professional laptop for work, and I need to use Etherreal. Etherreal needs the Ethernet card/dongle/chip to run in Promiscuous mode. I have heard that unblivably the thunderbolt Ethernet dongle does not support this, if so then the laptop will not pick all the packets on the wire. is this true ?

IMac :: Optical Drive And CPU Fan High Speed On Little Usage

Sep 23, 2010

I bought one of the new-gen iMacs last month--my first Mac! My computer will often start making a low-droning noise, and it sounds like a fan. I have iStat, and usually during this time it will say that my Optical Drive and CPU Fan are both running at around 4000rpm. This happens when there is very little CPU usage too. It's happening right now, and I only have firefox running.

PowerPC :: Are Intel IMacs Louder Than G5 IMacs?

Aug 17, 2006

This is a odd question, but are Intel macs louder than previous macs? I just recieved an Intel iMac as a replacement for my dead iMac G5 and both myself and my family has noticed a loud sound (Sounds like a needle playing on an old record player) which is coming from the iMac. My first iMac was very quiet, however when I start using the new iMac this odd sound keeps happening. Is this normal? I am just worried that this scratching sound might by evidence of something breaking down. Also the sound is a lot louder when under Windows XP.

PS: the sound is loud enough to be picked up on the internal microphone, however I don't know how to link the file to Macrumors.

Nov 4, 2009

Apple has released a new beta of the Mac OS X 10.6.2 update with fixes for various performance issues dealing with AirPort, graphics drivers, and Apple TV, among others.

Those familiar with the build, titled 10C540 have said that it contains fixes for AirPort performance issues on the newly released iMacs and also resolves a problem which arose when plugging and unplugging a system to an Apple TV. A VMWare fix is also included, presumably for the newly released Fusion version 3.0.

The new build also fixes reported panic issues with USB, Apple Filing Protocol, and some video cards.

In the 10.6.2 update, Apple plans on fixing and tweaking nearly 150 OS X components.

Some components slated for fixes include: AppleBacklight, Battery Menu, Dictionary, Expose, FileSync, Family Controls, Fonts, Front Row, HFS, Inkwell, iPhoto, MobileMe, OpenCL, Parental Controls, QuickTime, Screen Sharing, Spell Checker, Spotlight, Time Machine, and USB.

Mac OS X 10.6.2 is expected to be released sometime in November and will reportedly be around 480 MB in size.[ View this article at AppleInsider.com ]

IMac :: Trouble With Airport With New IMacs?

Aug 9, 2010

I looked through a few pages of threads and did not see this so here I go.Is there a problem with the new iMac and their airport card? I bought a new iMac 21.5" to replace my 20" early 2007 model and the internet stayed connected to my router for maybe the first few days but now it keeps disconnecting. It sometimes will reconnect once I turn the card off and then on again other time I need to restart the computer to get it to connect. There have even been a few times when a restart does nothing for the problem. This problem is not just a once in awhile thing. Just this morning, I worked on my computer for like 20 minutes and it disconnected itself about 5-6 times while just downloading some music in iTunes and surfing this forum.

Is this just me? or is this a wide spread problem? I want to know so I can take it to the Genius Bar if this is just me to have them fix it.

I have waited along time to upgrade my trusty imac g4. I know there is allot of negative remarks, about the new imac's. gfx card, glossy screen, and now there is some negative posts about the 20'' models using a low quality "tn" type lcd screen. which is lower quality than what was used in the last imac model line. Does any body know what was used in the last line of imac g4's late 2004. will this screen be comparable or worse than my g4?

MacBook Pro :: Fan Speed Is Constant High In MBP

Mar 22, 2010

Whenever i open an application both of the fans go to 6000+ rpm in a couple minutes give or take.Strangely web browsing doesn't cause this speed but if a youtube video is played it gets up there fast.Applications such as quicktime and logic gets up there no matter what is played.I have fan control and smcfancontrol, 40GB free, software updated, tried the reset thing (turn off, hold power button, boot), cleared printing operations.The only thing smcfancontrol does for me is it slows down the fans quicker whenever i close all my applications.

MacBook Pro :: 15" Fan Speed To High?

Jun 14, 2012

Lately my MacBook is making a lot of noise. I was at school working in Google Docs when suddenly a lot of noise came out of my MacBook and I think it's the fans. 

When I for example watch a YouTube video the noise starts and I'v never had that before. Also when I run my Minecraft server and Minecraft at the same time it starts spinning at 6175 RPM. I know those are resource heavy tasks but I've never had that before.

I installed smcFan to monitor my fans and the degrees (C°) goes from 49° to 91° when I open Minecraft. Early 2011 MacBook 15" on Lion 10.7.3

Mac Mini Is Slow And Its Fan Speed Is Very High

Jun 19, 2012

I have a 2011 mid range mac mini and love the machine, however I have noticed a few things.  First off, it seems to be a bit on the slow side when multitasking. I have the standard 4 gigs of ram installed, but running programs like MS Word and Safari at the same time, the machine seems to struggle a bit.  Also I have noticed when doing a lot of file transfers via USB, the fan will kick up to high gear for a few minutes and then drop down.  Is there something wrong or is this normal?  I'm doing a time machine backup of 120Gigs, have safari open and activity monitor open. Activity monitor states 1.16Gigs free, 792MB wired, 961.4MB active, 1.12GB inactive, 2.84GB used.  VM size is 150GB, page ins are 962, outs are 380kb, swap used is 10.5MB.  Right now the fan seems to have slowed to a mid range mode of some sort and is not in high gear.

MacBook Pro :: Fans Going At Extremely High Speed

Aug 22, 2009

I have a late 2007 macbook pro and recently the fans have been going at extremely high speeds without the MBP being hot at all. I have SMCFanControl and iStat Pro and both of them said my MBP's temperature was around 55C though the fans were going between 4000 and 6000 RPM, I also checked the activity monitor for high CPU usage but nothing high there. I turned my MBP off for 5 minutes with a fan blowing on it just incase it was hot but when I turned it back on the fans immediately jumped back up to 6000 RPM. They're back to normal now but I assume it will happen again. Anyone know what's wrong?

Intel Mac :: HDD Fan Speed High - Operating At 5500 Rpm

Feb 23, 2012

Returned home this evening to hear my iMac fan making lots of noise, upon checking it was the HDD fan that was operating at 5500rpm. Both other fans were normal. Ambient temperature was 23c and HDD temp was 36c. Normally it's almost silent. It's a late 2009 21.5" base model that has never had an issue in the 23 months that I have owned it. Any idea what the problem is has it gone bad? I restarted but the problem remained I had to shut down and restart to get it back to normal. On another note how do you clean off the dark grey blotchy marks that have appeared at the top of the screen. They don't appear to be on the glass. They started in each corner now they span entire screen top.

Ive got a pretty fast internet connection at home and I have just realised that when I plug my iBook and desktop pcs into my wireless router ethernet (LAN) ports I get a much faster internet connection speed compared to the wifi.I.e. 12-17mbps when through ethernet and when I connect to the wifi I get 2-4mbps. My computers are all located in the same room no more than 5 metres away from the router.

PowerPC :: Which RAM For Dual 2ghz G5 Give High Speed?

Nov 14, 2006

Crucial lists PC4000 (500mhz) as well as PC3200 (400mhz) for my Power Mac. It has 1gb of PC3200 in it right now. I always thought that you wanted your RAM to be AT LEAST as fast as your FSB. Well...my FSB is 1ghz per processor. SO, would it be a good idea to run PC4000 RAM as opposed to PC3200? From what I gather if I mix them, it will just run the RAM at 400mhz. So would it be substantially faster with say, 1gb of PC4000 as ooposed to 1gb of PC3200 ?
